My Notes Ask Your Teacher Two blocks, each of mass m = 3.90 kg are hung from the ceiling of an elevator as in the figure below (a) If the elevator moves with an upward acceleration a of magnitude 1.1 m/s2, find the tensions T1 and T2 in the upper and lower strings. (b) If the strings can withstand a maximum tension of 89.2 N, what maximum acceleration can the elevator have before a string breaks? m/s2 Need Help?Read It Submit Assignment Save Assignment Progress Home My Assignments Extension Reques WebAssigr 4 00 1997-2018 Advanced Instructional Systems, Inc. Al nghts reserved.Explanation / Answer
(A) Applying Fnet = m a On both mass system,
T1 - (m + m)g = (m + m)a
T1 = 2 (3.90) (9.8 + 1.1)
T1 = 85.02 N ..........Ans
now on lower mass,
T2 - m g = m a
T2 = 42.5 N ......Ans
(b) putting T1 = 89.2 N in first equation,
89.2 - 2(3.90)(9.8) = 2(3.90) a
a = 1.64 m/s^2 .......Ans
